Outcome Measures
Primary Outcome Measures
- Pressure threshold in hypogastrium that induces pain [day 30 after treatment initiation]
Pain threshold versus mechanical stimulation in hypogastrium (anterior central L2 dermatoma) measured in kPa
Secondary Outcome Measures
- Pressure threshold in dermatomes that induces pain [baseline, day 15, day 30 and day 45]
Umbral of pain versus mechanical stimulation in dermatomes L2 anterior, L2 posterior, and T1 of the dominant upper extremity.
- Temperature threshold in dermatomes that induces pain [baseline, day 15, day 30 and day 45]
Umbral sensation versus thermal stimulus (cold heat) in anterior central L2 dermatomes, posterior central L2, and T1 of the dominant upper extremity. Measured in ºC.
- Intensity of the general pain [baseline, day 15, day 30 and day 45]
Intensity of the general pain associated with endometriosis measured by a visual analogue scale (0-10)
- Anxiety and depression combined scale [baseline, day 15, day 30 and day 45]
Anxiety and depression measured with the Scale of Anxiety and Hospital Depression Scale (HADS).
- Quality of Life [baseline, day 15, day 30 and day 45]
Quality of Life measured through the EQ-5D-5L questionnaire.
- Central sensitivity [baseline, day 15, day 30 and day 45]
Central sensitivity measured with the Central Sensitization Inventory (CSI) questionnaire.
- Cognitive disorder measured by a list of words [baseline, day 15, day 30 and day 45]
Cognitive disorder measured by a list of words (immediate memory and retention) and digits (attentional capacity) of the Wechsler Memory Scale (WMS-III).
- about sleep quality [baseline, day 15, day 30 and day 45]
Visual analogue scale 0-10 about sleep quality
